Enough Nemesis to Go Around - S3-E1

Factual error: The 1-ton electromagnet is supposed to have moved only the bullets without affecting the steel elevator car at all. This is impossible.

One Watson, One Holmes - S3-E19

Character mistake: Sherlock says "Cherchez la femme" but pronounces "femme" as "fem" rather than "fam." In earlier episodes, he has been seen speaking fluent French, and so would be unlikely to make so basic an error. (00:16:30)

One Watson, One Holmes - S3-E19

Factual error: In the scene in the hospital, the guy who drove his motorbike into a van has an IV canula in his right hand, but the IV pole and the IV bag are on the left side of the bed, which means the IV line has to be long enough to go up to the bedhead, then behind the bedhead and then up to the bag, leaving no way to check for air bubbles.

The Best Way Out Is Always Through - S3-E22

Continuity mistake: When Bell and Holmes are looking at the files, there's an open book next to Bell. When he starts texting, with both hands, the book becomes closed in one shot and then back open in the next.

Absconded - S3-E23

Factual error: Holmes shows an epinephrine auto-injector, but it is only a training device without any needle or medicine: 1. The real epinephrine auto-injector has a transparent housing to enable the user the check of the solution inside the cartridge. The shown "device" has only a grey, opaque housing, as the training device has. 2. The real epinephrine auto-injector has an orange-colored needle guard in the form of a hollow body. The shown "device" has only a finned dummy. (The real epinephrine auto-injector (single use device) is sold with a training device (reusable) to let the user practice the application once or multiple times). (00:25:50)
